ParadeDB is an open-source PostgreSQL extension that brings Elasticsearch-quality full-text search and analytics directly into Postgres, removing the need to copy data into a separate search engine. Built in Rust on the Tantivy library, its pg_search extension delivers BM25-ranked search, faceting, and columnar analytics while preserving Postgres ACID guarantees and avoiding the brittle ETL pipelines that connect Postgres to Elasticsearch. Founded in 2023 by Philippe Noel and Ming Ying and backed by Y Combinator and Craft Ventures, ParadeDB raised a $12M Series A in 2025 and counts Alibaba, Modern Treasury, and Bilt Rewards among its users.
Spiral is a New York-based data infrastructure company building a database reimagined from the ground up for the AI era - what it calls the 'Third Age of Data,' when machines, not humans, are the primary consumers of data. Built on Vortex, an open-source columnar file format donated to the Linux Foundation, Spiral streams data directly from object storage into GPU memory, unifies governance across every data type from tiny embeddings to massive video, and aims to keep expensive GPUs saturated instead of idle. Founded by ex-Palantir and ex-Citadel engineers, it emerged from stealth in September 2025 with $22M in Seed and Series A funding led by General Catalyst and Amplify Partners.
Josh Lospinoso is the co-founder and former CEO of Shift5, an observability and cybersecurity company that protects the onboard operational technology of planes, trains, tanks, and ships. A West Point graduate, Rhodes Scholar, and Oxford-trained statistician, he spent more than a decade as an Army cyber officer building elite hacking tools for the NSA's Tailored Access Operations and the Cyber National Mission Force. Before Shift5 he co-founded RedOwl Analytics (acquired by Raytheon/Forcepoint in 2017). He wrote the C++ course that U.S. Cyber Command uses to train junior developers and turned it into the book C++ Crash Course. In January 2026 he moved from CEO to the board to focus on long-term vision while Shift5, having raised more than $180M, scaled past 130 employees.
LanceDB builds the data backbone for multimodal AI. Its open-source Lance columnar format and lakehouse let teams store, search, and train on text, images, video and embeddings in one system - replacing the brittle stack of Parquet files, vector stores and feature pipelines that AI teams usually stitch together. Used by Midjourney, Runway, Character.AI, WeRide and others, LanceDB raised a $30M Series A in 2025, bringing total funding to roughly $41M.
Will Manning is the co-founder and CEO of Spiral, a New York data company building infrastructure for the moment machines became the main consumers of data. He spent nearly a decade at Palantir co-creating and scaling Foundry, then set out to fix a bottleneck nobody else seemed bothered by: GPUs that can swallow terabits per second, fed through legacy file formats that make CPUs decompress everything first. His answer is Vortex, an open columnar format he donated to the Linux Foundation, and Spiral, the exabyte-scale system built on top of it. Spiral launched from stealth in September 2025 with $22M from Amplify Partners and General Catalyst.
Zach Lloyd is the founder and CEO of Warp, the Rust-based terminal that grew up into an agentic development environment. A former Google principal engineer who led the Docs and Sheets teams, he looked at the one tool every programmer touches and noticed it had barely changed in 40 years. Warp's answer: a command line that reads natural language, runs AI agents, and as of 2025 codes by prompt. The company has raised roughly $73-75M from Sequoia, GV, Dylan Field and Elad Gil, and went from its first $1M of ARR in 300-plus days to adding $1M every few days.

He is based in Gdansk, Poland.
Mozilla builds Firefox and a family of privacy-first internet products with a single, stubborn goal: keep the web open, private, and not owned by anyone. Spun out of Netscape in 1998 and run by a for-profit corporation wholly owned by the non-profit Mozilla Foundation, Mozilla competes with the largest companies on earth while answering to a mission instead of shareholders.
